Soil-Transmitted Helminths, Poverty, and Malnutrition in Honduran Children Living in Remote Rural Communities

Soil-transmitted helminth (STH) infections are endemic in Honduras, but their prevalence according to the levels of poverty in the population has not been examined. The present cross-sectional study is aimed to determine the role of different levels of poverty in STH prevalence and infection intensity as well as the potential associations of STH infections with malnutrition and anemia. Research participants were children attending a medical brigade serving remote communities in Northern Honduras in June 2014. Demographic data were obtained, and poverty levels were determined using the unsatisfied basic needs method. STH infections were investigated by the Kato-Katz method; hemoglobin concentrations were determined with the HemoCue system; and stunting, thinness, and underweight were determined by anthropometry. Data were analyzed using descriptive statistics and univariate and multivariable logistic regression models. Among 130 children who participated in this study, a high prevalence (69.2%) of parasitism was found and the poorest children were significantly more infected than those living in less poor communities (79.6% vs. 61.8%; P = 0.030). Prevalence rates of Trichuris trichiura, Ascaris lumbricoides, and hookworms were 69.2%, 12.3%, and 3.85%, respectively. In total, 69% of children had anemia and 30% were stunted. Households’ earthen floor and lack of latrines were associated with infection. Greater efforts should be made to reduce STH prevalence and improve overall childhood health, in particular, among the poorest children lacking the basic necessities of life.

Helminths of toad Rhinella icterica (Bufonidae), from the municipality of Botucatu, São Paulo State, Brazil.

Fifteen specimens of bufonid toad Rhinella icterica (Spix, 1824), 7 males and 8 females, collected in the municipality of Botucatu, São Paulo State, Brazil, from March 2002 to January 2003, were examined for helminth parasites. All toads were infected with at least one parasite species (overall prevalence = 100%). Five helminth species were found, including four nematode species, Rhabdias fuelleborni Travassos, 1926, Oswaldocruzia subauricularis (Rudolphi, 1819), gen. sp. no identified Cosmocercidae Travassos, 1925 and larvae of Physaloptera Rudolphi, 1819, and one acanthocephalan species, Acanthocephalus saopaulensis Smales, 2007. Rhabdias fuelleborni and A. saopaulensis were the most abundant species. Except for Physalopteridae larvae, all helminths occur in high prevalence (> 70%). All helminth species presented a distribution toward to more aggregated pattern in these host samples.

Helminths of lizards from the municipality of Aripuanã in the southern Amazon region of Brazil

Ninety-five specimens from 13 species of lizard collected during a herpetofaunal monitoring programme of the Faxinal II power plant, municipality of Aripuanã, state of Mato Grosso, Brazil (southern Amazon region) were examined for helminths. A total of 21 helminth species (16 Nematoda, 1 Cestoda and 4 Trematoda) were recovered, with an overall prevalence of 67.37%. Seventeen new host records and seven new locality records are reported. A low number of specialists and core helminth species were found. Lizard body size was positively correlated with both the total number of helminth species and individuals. Active foragers exhibited higher helminth diversity. However, sit-and-wait foragers, especially Plica plica, had similar diversity values as active foragers and harboured more helminth species. The degree of similarity in helminth fauna was higher among closely related host species. Copyright © 2011 Cambridge University Press.
